The Industrial Master Station, AA703, is a processor-controlled master station with full keypad, used in the Pro700 “all-to-all” intercom system that has no exchange unit. The AA703 is surface mounted and is designed to be splash-proof for use in humid and dirty conditions. The cabinet is made of flame-retardant and shock-resistant Bayblend plastic.

The station has a built-in loudspeaker and microphone and is wired in parallel via a 2-pair cable in a star or bus configuration. A third pair can be installed for a program distribution channel for music, etc.

The AA703 has a duplex speech option, while simplex speech can be controlled by pressing/releasing the T-button. The station is easily programmable through internal switches. The station has an internal 3 W amplifier. The volume of the internal loudspeaker can be adjusted incrementally via internal switches. An external 20 ohm loudspeaker may also be connected.

An optional 10 W amplifier, FC740, may be plugged in on top of the internal PCB. If required, the FC740 also enables using the external loudspeaker both as loudspeaker and microphone (talk-back function).

The AA703 has a built-in relay which can be used for controlling cameras or door locks. The keypad is normally used for selective dialing to all stations, from call numbers 10 to 49. A direct-call function can be programmed to single-touch keys for the following number ranges: 10-19, 20-29, 30-39 or 40-49.
